The user unleashes a volley of shuriken with one hand, and at the same time, exhalesfire-infused chakra onto them in order to increase the weapons' destructive potential by making them capable of inflicting severe burns upon direct contact with either the intended victim, or any other object caught within their trajectories.

Due to the chakra-based nature of the flames that surround them, the shuriken will continue to burn after impact, regardless of the flammability of the object that they ultimately collide with.

Trivia

Hōsenka (鳳仙化) is the Japanese name for the Impatiens balsamina. Tsumabeni (爪紅) is an alternative name for this plant, stemming from its use in producing red dyes for nail polish.

In chapter 56, Sasuke uses a rudimentary form of this technique employing the Fire Release: Phoenix Sage Fire Technique and hiding shuriken within the flames for an added surprise attack. However, that tactic and this technique should not be confused with each other, as this one employs chakra flow — breathing the flames directly onto the shuriken.
